Bulb Mode with Adjustable Aperture for LC-A


Looking for a solution to set your LC-A to bulb mode? But your shutter won’t compromise when you adjust your aperture for bulb?

Theres no need for internal or external modification to make this thing happen. All you need is:

1. Your LC-A
2. A little patience

First of all, just open a battery cover on the bottom of your LC-A, and you will see the symbol for the positive terminal. What you need to do is take out all the batteries and put them back in the opposite direction, which means position the positive end of your battery beside the negative terminal. That’s all! But this trick only works with LC-A and not LC-A+.

Now you can enjoy capturing light trails and other experiments.

Here is a link to a video on how to do this tip: LC-A bulb mode with adjustable aperture.

    Oh wow, gotta try this! Not going to blow it up or anything? I know their is a bulb trick with the xa too, should try them both out really!

    couldn't you just cover the light meter with ur finger/black tape?

    NOOOOO! ICANT BELIEVE!! (sorry for capital letters) This is the greatest tips ever publisherd here! It's not a joke?

    I've just try it....It only work ONE time then you have to put the batteries on again in the right way and then reverse it again to work it again!

    On my LC-A doesn't work! :-S

    well. I've see the video, I don't know why but with my 3 LCA's it work only once then I have to repeat all the process..

  8. superlighter

    it seems that it work better with the oldest LCA models

    Doesn't work at all on my old 1986 LC-A..... :(

    Same on my 1989 LC-A :-(

    Doesn't work on my '86 model either :-( The XA bulb hack does work with mine though :-)

    maybe it depend on the batteries type, silver oxide vs alkaline tipe (sr44 or lr44), however, I've had some successfully multiple Bulb with the oldes LCA I have, the one with the electric contacts on the bottom.

    @cinzinc : if just cover the light meter with ur finger/black tape, when u change the apperture shutter speed 1/60s is set automatically :)
    @superlighter , @marant69, @vicuna , @nicolas_noir . : maybe all of you can try with the new battery because it need a full voltage of battery power , it also happen to me before.after change the battery it working again.
    @analogmonolog : thx.. try dont think
    @johann_affendy : x kot effect kt batt je
    @chethong : reverse the circuit maybe!?!
    @mandecster : :D
    @eastmoe : puek
    @naqi : get one!!
    @kamalfaiz91 : dh buat byk kali ok jer.. :|

    dont do this for a long time period because it will cause your battery low power more faster :s

    tried first and if it is harmful to you LCA do not continue, but at least we know that the tipster is effective
    good idea,nice pics,great tips. well done amar. congrats!

    lca+ faulty aku selalu jer bulb.xyh ssh2 tukar bateri..puek

    Tidak berhasil di LC-A+, lampu indikator tidak menyala dua-duanya. ;D
    Think this is harmful for the electronic parts inside your LC-A, like diode : to allow an electric current to pass in one direction (called the diode's forward direction), while blocking current in the opposite direction (the reverse direction) - what wikipedia says.

    @ho0la you've just revealed an awesome tipster! awesomeee for those who succed!

    @ripsta : thx amigos :0
    @eastmoe : puek
    @istionojr : untuk LC-A+ memang tidak bole menjadi :|

    Harmful.. Will it hurt the diodes, resistors and others, no.. .. But Im sure there is a chip in there for controlling the shutter and if any polarized capacitors (not likley in there, but you never know ), those may be damaged by a reversal. Time will tell if it damages the chip. I would not be reversing batteries on a 20+ year old camera, just my opinion on 25 years of electronic repair.

    This is very risky. There's a huge possibility that this will fry the electronics of your camera.
